STOVE-PIPE DRUM.

Specification forming part of Letters Patent No. 59, 173, dated October 30,1866.

To all whom it may concern:

Be it known that I, EDWARD S. BLAKE, of the city of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Radiators; and I do hereby declare the followin g to be a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature ofmy invention consists in constructing a radiator so that the soot, dust, and other refuseof combustion will tend by its gravitation to collect to one point when released from the shell of said radiator; also, in providing said radiator with fines, openings, and a valve, the whole being constructed, arranged, and operating substantially in the manner hereinafter described.

To enable others skilled in the art to make and use my invention, I will proceed to de scribe its construction andoperation.

In the accompanying drawings, Figure 1 represents a perspective view of my improved radiator attached to an ordinary heatingstove. Fig. 2 represents a longitudinal section of my improved radiator.

In the accompanying drawings, A represents an ordinary heating-stove. B represents the radiator, which consists of two hollow columns, l and m, which rest on an inverted arch, m, and are surmounted with a hollow arch, y. The columns and arches are constructed, arranged, and attached together so that they form an undivided and continuous chamber for the heat and smoke to pass through.

It represents the flue through which the heat and smoke enter the chamber of the radiator. 0 represents the exit-flue of the radiator. J represents the valve used for directing the course of the smoke and heat.

f represents an opening which is placed in the upper part of the arch y. This opening is provided with a cap, (marked 0,) and is used for the purpose of cleaning and sweeping down the soot, dust, &c., which may have collected in the radiator.

0 represents a capped opening which is placed in the inverted arch a. This opening is arranged so that it will come directly opposite to the center of the exit-flue O, and is used for cleaning out said flue.

When the valve J is placed in the position represented by the dotted lines marked 4, then the smoke and heat will pass up and around in the radiator B, as indicated by the arrows marked 1; and when the valve J is placed in the position represented by the dotted lines marked 3, then the smoke and heat will pass up through the flue R and 1 into the exit-flue G, as indicated by the arrows marked 2.

The advantages of my improvement in radiators consist, first, in providing a free and unbroken course for the heat and smoke; second, in controlling the course of the heat and smoke by the arrangement of the valve J, causing it to pass entirely around through the radiator, or allowing it to pass off direct into the exit-flue; third, in bringing the entire shell of the radiator in contact with the heat; fourth, in so constructing and arranging the radiator that the soot and dust will have a tendency by its own gravity to fall back into the tire; fifth, in providing openings for cleaning the shell and exit-flue of the radiator, said openings being so arranged with relation to the general construction of the radiator that in cleaning it all the soot and dust, &c., will fall back into the fire.

I wish it clearly understood that I do not confine the construction of my improvement in radiators. to any form or size of the several parts described and set forth, for these may be varied to suit the taste, skill, judgment, and pleasure of the mechanic; but in every case the same general plan and principle of construction must be followed, substantially as herein described, in order to obtain the results herein set forth.

Having thus described the nature, construction, and operation of my improvement, what I claim is- A radiator so constructed that the soot, dust, and other refuse of combustion will tend by its gravitation to collect to one point when released from the shell of said radiator, substantially as herein described, and for the purpose set forth.

2. The radiator B, provided with lines R and O, openings 0 and f, and valve J, constructed, arranged, and operating substantially as herein described, and for the purpose set forth. I

E. S. BLAKE.
